drm/amd/display: For stereo keep "FLIP_ANY_FRAME"
[Description] Observed in stereomode that programming FLIP_LEFT_EYE can cause hangs. Keep FLIP_ANY_FRAME in stereo mode so the surface flip can take place before left or right eye Reviewed-by: Martin Leung <Martin.Leung@amd.com> Acked-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Alvin Lee <alvin.lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
